The following are actual case examples of people that have come to us with various different situations and serve to illustrate
what is achievable. You will almost certainly be able to find one that is similar to your own situation.
MARK. C – MYOPIC
Mark is a 23 year old recent IT graduate. He had just started a new job in his area of expertise and had worn glasses since his early teens. He was keen to eliminate his glasses completely.
His prescription was straight forward enough.
Right eye -3.00/-1.5 x 90 (three diopters of short sightedness with 1.5 diopters of astigmatism)
Left eye -3.25/-2.00 x 85 (three and a quarter diopters of shortsightedness with 2 diopters of astigmatism)
This was a very common and straight forward prescription and well within the 9 diopters of the upper limit for lasik.
His eye examination was completely normal and his scans were also completely normal.
We performed Lasik with Intralase with resultant 6/5 vision in each eye after his procedure (6/6 is 20/20 vision and 6/5 is
even better than that.
CATHY. S – HIGH MYOPE
Cathy was a 28 year old nurse. She had worn glasses most of her life and was completely unable to see without her glasses.
She too was keen to be free of her glasses.
Her prescription was unfortunately a problem.
Right eye -11/-0.25 x 77 ( eleven diopters of shortsigthtedness with only a quarter of a diopter of astigmatism)
Left eye -12/-0.5 x 80 (12 diopters of shortsigthtedness with half a diopter of astigmatism)
This meant that neither Lasik nor PRK could be undertaken as her prescription was out of range for these procedures.
Due to her young age, refractive lens exchange was also not an option as it would render her instantly presbyopic.
Thankfully she only had a small degree of astigmatism which made her a good candidate for a phakic intraocular lens.
She had Alcon Artisan lenses implanted with resultant vision of right 6/6 and left 6/7.5.
She thus achieved her goal of freedom of glasses.
ROBERT. S – HYPEROPE
Robert was a 44 year old plumber. He too had worn glasses most of his life and was experiencing increasing difficulty at
work. He was frequently in cramped conditions and was finding seeing near objects a real problem. He was wearing
multifocal glasses but found that placing his head in the right position to see near a real problem.
His prescription was relatively straight forward but as he was 44 he had the additional problem of presbyopia to deal with.
Right eye +1.5/-0.25 x 2 (one and a half diopters of long sight with quarter of a diopter of astigmatism)
Left eye +1.75/-0.75 x 15 ( one and three quarter diopters of long sight with three quarters of a diopter of astigmatism)
Correcting his long sightedness was relatively straight forward enough, however this would not entirely solve his problem as he would still have problems dealing with things up close.
We performed a therapeutic trial of monovision using contact lenses to see if he liked it.
As he was left eye dominant, we fitted a contact lens in his left eye leaving him deliberately short sighted. In the right we fitted a
contact lens to fully correct him.
This proved a success with Robert reporting excellent vision for near and far. We therefore proceeded to Lasik with Intralse with a resultant happy patient.
SUJILLA. S – HIGH HYPEROPE
Sujilla was a 54 year old accountant. She had worn glasses since age 7 and was keen to be free of them.
Her script and age however presented a significant challenge.
Right eye +4.00/-1.5 x 67 ( four diopters long sighted with one and a half diopters of astigmatism)
Left eye +3.75/-1.5 x 80 ( three and three quarters diopters of long sight with one and a half diopters of astigmatism)
Due to her high hyperopic prescription, she was out of the range for Lasik or PRK. Further, she did not take well to a monovision
trial with contact lenses. Her anterior chamber depth was only 1.9mm in each eye which meant that a phakic intraocular lens was also not an option.
Her only option therefore was a refractive lens exchange with intraocular lens implantation. This was performed with the goal of
leaving her with good distance vision without glasses. For reading she was happy to wear reading glasses.
Although she did not fully achieve her goal of complete glasses independence, she was happy enough to have achieved independence from distance glasses and was not too troubled about having readers.
